Abstract
A method includes directing a probe beam to a target that includes an array of data portions in a data storage medium arranged so that a beam area of the probe beam extends across a plurality of adjacent data portions, the array including a data portion subset with each data portion of the subset responsive to the probe beam to produce a response illumination, receiving the response illumination at a detector, and determining data values corresponding to the plurality of adjacent data portions based on the received response illumination. Apparatus and systems are also disclosed.
Claims35
A method, comprising:
- directing a probe beam to a target that includes an array of data portions in a data storage medium arranged so that a beam area of the probe beam extends across a plurality of adjacent data portions, wherein the adjacent data portions are responsive to the probe beam to produce a mixed response illumination;
- detecting the mixed response illumination at a detector;
- and
- determining data values corresponding to the plurality of adjacent data portions based on the detected mixed response illumination.
An apparatus, comprising:
- a data storage medium that includes an array of data markers;
- a probe beam source situated to produce a probe beam having a beam area at the array that extends over a plurality of data markers;
- a scanner situated to scan the probe beam across the array of data markers;
- an optical detector situated to detect a response illumination produced by the plurality of data markers in response to the probe beam and provide a mixed response illumination signal;
- and
- a computer configured with a super resolution solver so as to determine values of the array of data markers based on the mixed response illumination signal.
A system, comprising:
- a memory coupled to at least one processor, the memory storing matrix data associated with an array of data markers of a storage medium;
- and
- a computer-implemented super resolution solver, stored in the memory, the super resolution solver for determining values stored in the data markers of the array based on a plurality of mixed response illumination probe beam measurements of the array, wherein an area of the probe beam extends over a plurality of adjacent data markers of the array to produce the mixed response illumination so that signal portions of the adjacent data markers in the mixed response illumination probe beam measurements are used by the super resolution solver to determine the values of the adjacent data markers.
An apparatus, comprising:
- an optically stimulated luminescence (OSL) storage medium including an array of OSL data markers situated to illuminate in response to optical stimulation;
- a probe beam source coupled to the OSL storage medium and situated to produce a probe beam spot that extends over a plurality of OSL data markers in the array so as to provide optical stimulation to the plurality of the OSL data markers;
- a detector coupled to the array and situated to detect a mixed illumination response beam corresponding to the optical stimulation of the plurality of OSL data markers;
- and
- a processor configured to determine values of the plurality of OSL data markers based on the detected mixed illumination response beam.
A data storage medium, comprising:
- an array of data portions configured on a substrate to receive a beam area of a probe beam configured to read the array of data portions by extending as a diffraction limited spot across a plurality of adjacent data portions and causing each of the adjacent data portions to emit a respective component illumination associated with a data value to produce a mixed response illumination configured to be detectable so that the data values are deconvolvable from the detected mixed response illumination.
